Cast Iron Check Valve

Cast iron boiler check valve is a kind of valve used to control the one-way flow of media, its main role is to prevent media back flow, to ensure the normal flow direction of media. This valve is widely used in various fields, such as tap water, industrial pipelines, sewage treatment, power generation, metallurgy, shipbuilding, paper making and so on. Cast iron boiler check valve can prevent the backflow caused by medium siphon, avoid the fluid in the pipe system to produce confusion, to ensure the correct direction of fluid flow and stability.

In addition, cast iron boiler check valves help reduce piping stress losses and protect equipment and valves. For example, after the pump is closed, cast iron boiler check valves can prevent media backflow, thus protecting the pump and valves, such as equipment, extend its service life.

The main types of cast iron boiler check valves include swing check valves and lift check valves. Swing type boiler check valve is suitable for large diameter pipeline, with the characteristics of fast closing and starting, can avoid the backflow of pipeline media and water hammer and so on. The lifting boiler check valve depends on the flow of the media itself and automatically open and close the valve disc, also used to prevent media backflow.

To sum up, the role and purpose of cast iron boiler check valve is to prevent media backflow, ensure the normal flow direction of media, but also help to reduce pressure loss in the pipeline, protect equipment and valve.
